Shock

Question 1

Haemodynamic changes in hypovolaemic shock

Answer 1

Low CVP and pulmonary artery occlusion pressure (PAOP),
Low Cardiac output
Increased systemic vascular resistance

Question 2

Haemodynamic changes in pulmonary embolism

Answer 2

Low cardiac output, high CVP, high pulmonary artery pressure but low PAOP

Question 3

Haemodynamic changes in cardiogenic shock

Answer 3

Signs of myocardial failure, increased systemic vascular resistance, CVP and PAOP high (except when hypovolaemic)

Question 4

Haemodynamic changes in anaphylaxis

Answer 4

Low systemic vascular resistance, low cvp and PAOP, high cardiac output

Question 5

Haemodynamic changes in septic shock

Answer 5

Low systemic vascular resistance, Low CVP and PAOP, check Kumar and Clarke

Question 6

Haemodynamic changes in cardiac tamponade

Answer 6

Parallel increases in CVP and PAOP, low cardiac output, increased systemic vascular resistance.

Question 7

First agent for vasoactive shock

Answer 7

Norepinephrine
